A new stroke and a dementia related disease called dementia are on the rise, according to a new report.
The report, published in the Journal of the American Medical Association (JAMA), said the number of people living with dementia in the U.S. is expected to reach 1.6 million by 2050, up from about 1.1 million in 2016.
The report found the most prevalent dementias are dementia caused by a degenerative brain disease and the rare form of dementia caused when the brain’s ability to communicate with its central nervous system is damaged.
More: The National Institutes of Health has identified the cause of dementia, and is working on a drug that could slow or stop it, the report said.
The JAMA study said there were 2.3 million people with dementia diagnosed in the United States in 2016, up more than 3 percent from the previous year.
About 1.4 million people had dementia in 2016 and were considered to be at increased risk of dementia.
The number of dementia cases in the next decade is expected in the millions, the study said.
It found the rise in dementia was largely due to the use of new drugs that are targeting the central nervous systems and are being tested in humans.
These drugs, such as neuroleptics, are being developed by companies like Pfizer and AbbVie.JAMA said the pharmaceutical companies were developing new drugs for the neuroleptic drug amyloid beta, which is used to treat Alzheimer’s disease.
The drug is approved for use in people over 65.
But the researchers said that a drug approved in 2014 called Zalmanza has also been linked to dementia, increasing the risk of the disease.
